Pocket AA allows you to "step on the gas" already on the first betting round. Aces are almost always willing to go for stack preflop.AK and AQ will bring a good profit if they hit top pair. Many opponents are unfamiliar with the concept of "dominance" and are willing to pay two or three streets with aces, kings, or queens. It's hard for a beginner to give up when they hit top pair of aces. The kicker becomes secondary for them.
